Cardiopulmonary resuscitation (CPR) is a lifesaving skill performed during the cardiac arrest. Various factors of rescuer affect CPR quality, and rescuers physical fitness is one among the important factors needs to be explored for improved CPR quality. This study aimed to assess the physical activity (PA) levels of the health care providers (HCPs) who were trained in basic life support (BLS) and its relationship on chest compression duration, hemodynamic parameters, and fatigue levels of the rescuers.
A single-center, cross-sectional study was conducted on 48 HCPs who were trained in BLS within one year. Eligible participants were contacted by email, and the responders' level of PA was determined using the global physical activity questionnaire (GPAQ). The participants were recruited for chest compression-only cardiac arrest scenarios. Each subject performed continuous chest compression on the manikin until they perceived maximum fatigue. Heart rate (HR), blood pressure (BP), oxygen saturation (SpO), and fatigue level were assessed at baseline, immediately after and following two minutes of cessation of chest compressions. The total duration of chest compression was also documented.
Most participants (24, 50%) reported high levels of PA while 22 (45.83%) and 2 (4.17%) reported moderate and low intensity of PA, respectively. The mean age of the 35 participants was 26.08 ± 4.60 years. The mean duration of chest compressions was 193.25 seconds with higher times reported for those with high PA when compared to those with moderate PA ( = 0.017). Similar findings were also observed for fatigue.
Rescuers who reported high PA had lower levels of fatigue and could perform longer duration of chest compressions.

心肺复苏（CPR）是在心脏骤停期间实施的一项挽救生命的技能。施救者的各种因素会影响心肺复苏质量，而施救者的身体素质是为提高心肺复苏质量需要探索的重要因素之一。本研究旨在评估接受过基础生命支持（BLS）培训的医护人员（HCPs）的身体活动（PA）水平，及其与胸外按压持续时间、血流动力学参数和施救者疲劳程度之间的关系。
对48名在一年内接受过BLS培训的HCPs进行了一项单中心横断面研究。通过电子邮件联系符合条件的参与者，并使用全球身体活动问卷（GPAQ）确定应答者的PA水平。招募参与者进行仅胸外按压的心脏骤停模拟场景。每个受试者在模拟人上持续进行胸外按压，直到他们感到极度疲劳。在基线、胸外按压停止后立即以及停止两分钟后评估心率（HR）、血压（BP）、血氧饱和度（SpO）和疲劳程度。还记录了胸外按压的总持续时间。
大多数参与者（24名，50%）报告PA水平较高，而分别有22名（45.83%）和2名（4.17%）报告PA强度为中等和低强度。35名参与者的平均年龄为26.08±4.60岁。胸外按压的平均持续时间为193.25秒，与中等PA水平的参与者相比，PA水平高的参与者报告的时间更长（P = 0.017）。在疲劳方面也观察到类似的结果。
报告PA水平高的施救者疲劳程度较低，并且能够进行更长时间的胸外按压。
